ISSUE FOCUS 58 FEED & ADDITIVE MAGAZINE September 2024 Phytogenics comprise of a relatively infant department of feed additives that are gaining considerable interest within the aquaculture industry. A wide spectrum of phytogenics, particularly those containing terpene and saponin compounds, are increasingly supplemented in aquafeeds, due to their antimicrobial, immunomodulatory, antioxidant, anti-inflammatory, and growth promoting properties. OVERVIEW OF GLOBAL AQUACULTURE TRENDS Aquaculture is continuously expanding as a consequence of the demand for healthy and nutritious food; which, along with the global saturation of wild fishery production, has encouraged considerable growth of the sector. It is currently the fastest growing food producing sector in the world, growing at a rate between 5.6 to 7.8% per year. The Food and Agriculture Organization (FAO) estimates the global yield of wild fisheries to achieve 91 million tonnes in 2030, barely 1% higher than that in 2016. Contrastingly, the predicted annual production for aquaculture is 109 million tonnes by 2030, approximately 37% higher than that in 2016. Although aquaculture has accelerated rapidly, the diversification and intensification of its practices have been implemented to sustain high production levels; which, correspondingly, necessitates substantial quantities of high-quality, affordable, and sustainable feed ingredients to achieve maximum production performance. Recently, interests have shifted towards using innovative feed additives, such as phytogenics, to enhance the value of aquafeeds and improve the health and growth performance of aquaculture species. WHAT ARE PHYTOGENIC FEED ADDITIVES? Phytogenics, also known as phytochemicals, photobiotics, or botanicals, are natural bioactive compounds that are derived from herbs, spices, or other plants and incorporated into feedstuff with the aim of improving animal health and growth performance. Essential oils constitute a concentrated form of phytogenics, comprising mainly of the bioactive compounds of the plant, such as terpenes and polyphenols. The dietary supplementation of essential oils, such as oregano essential oil (OEO), demonstrates a simple, yet proficient approach to enhance the productivity of aquaculture species. COMPLEX MODE OF ACTION OF OREGANO ESSENTIAL OIL OEO, as an aquafeed additive, can provide an unwavering number of benefits, with a well-documented efficacy in improving the health status and growth performance across numerous aquaculture species including, but not limited to, Nile tilapia PHYTOGENICS: ELITE FEED ADDITIVES FOR AQUACULTURE SPECIES Gerred Fuchs Aqua Technical Sales Manager Anpario plc
